never can escape the exhausting old people, huh?


Given my age, you might soon have to again apologize for what you yourself called a "cheap jab":

I would suggest you switch to learning from experience. It is a rewarding intellectual ...

So this method will not work on the PCB side?

I don't have tools like that at my disposal so I couldn't try it. Don't see why it wouldn't work.

I have played with dozens of these calculators and they all fail in the same way lol.

Now that I'm looking at it... I don't understand how exactly this ribbon is electrically connected to the display in the first place. I am not seeing any connecting terminals on the LCD side, it's like it's ...

The issue has nothing to do with capacitors. The conductive adhesive used to attach the display ribbon gets weak with age, effectively disconnecting the display. I've experimented with new adhesive but it's nearly impossible to apply it in a way such that no contacts are bridged but there's ...

Sorry, best I can do is $50 try and replace electrolytic capacitors in the PCB and hope that was the cause of some calculator issues on Focus boards (which is what I am hoping to try within the next couple of weeks). Anything more complex than replacing components is currently beyond my comfort ...

She died of thyroid cancer in middle age a few years ago.

I hope yours is well.

I'm sorry to hear that. Having lost both my grandfathers to cancer (one skin, one brain) I know how much it hurts. Apologies for any hurt from my cheap jab.

by the way, you could also try rewriting the original firmware on the original controller. assembly is not that hard, you can just watch a 12 minute and 33 second youtube video and it'll tell you all you need to know. for reference, here's the instruction set for the intel 8051, a derivative of ...

I'm not sure why you'd want to use a teensy, the 32u4 it has is quite slow and only has a measly 2.5k of ram. quite unfit for a keyboard controller! I suppose you could bit-bang a clock-divided (7/16ths) bus speed dual-duplex serial port on an stm32 though that could potentially bottleneck the ...

Exactly. Credit is due to Pandrew, all the contributors to QMK, and to Xwhatsit. We’re all using derivatives of his work, for better and for worse: namely the 32u2 at the heart of it.


you're exhausting, jesus christ.

Thanks! :mrgreen:

Read NathanA’s struggles with that miserable chip on ...

you're exhausting, jesus christ.


32u2 is a bad chip. A true, new controller would dump that crap and go Arm or the like, and open up the software possibilities while also being cheaper and quicker to source!


since you clearly know better than everyone when it comes to this, i want you to ...

i hate it too but i'm not thankful for this piece of shit

Serious bad , my friend. It's coming - this winter. It has been planned for decades . I see the plan. (..."I see plans within plans"... sorry, Dune quote)

Hopefully, I'm wrong, nothing will happen and everybody can laugh at me like school girls on helium. I don't think I'm wrong. So far, I ...

I'm by no means a chemist but I remember learning about the cure profiles of friction materials and how it effected the formation of various surface molecules. They all behave differently, some tougher, some smoother, etc. It's a balance to get them correct for the application.

Your end result sounds great, gj!

I've always just stirred them in a mug with no issues.

Been out for a while, is the wax mod still the current "works fine" solution, or any new method with repeated good results?


boilwax has always been and will continue to be the best way to restore alps to nos condition. nek continues to wish for something else presumably cause he can't ...

500 is not firm price. Send me offers!

Sheepless wrote: 15 May 2022, 00:13 Interesting. Is this replacement calculator related to the one for the FK-9000 in Chyros's "project F" video?

No but I did design one for a 9000/5001 too. I'll sell em eventually just need to get around to writing the post.

For sale is my Focus FK-3002. This is an extremely rare Escom-branded black model that I have designed a fully-custom OLED calculator replacement for. I have also cleaned the board thoroughly and waxboiled the pine white Alps SKCM switches. They feel and ...

phew

still good prices, glws frog

there is only one possible reason for wanting a dog lubed up. deskthority's finest, everyone

I was watching this auction and was surprised to see the selling price. I know it’s a great blue alps board but I didn’t think it commands such a high price. Is there something I’m missing here?
